RAILWAY-TRACK CONSTRUCTION.

Specification of Letters Patent.

Patented June 25, 1907.

Application liled March 20,1907. Serial No. 363.3771

.To all whom t may oonccrm Be it known that I, Jol-1N H. F. SI-IULZE, acitizen of the United States, and a resident of the city of New York,Jamaica, borough of Queens, in the county of Queens and State of NewYork, have invented a new and ImprovedRailway-Track Construction, ofwhich the following is a full, clear, and exact description.

The purpose of this invention is the provision of a railway track ofsubstantial build without the use of ties, and in which that side of therail which is worn or otherwise damaged may be taken up and replacedwithout interfering with the opposite side thereof or the trafficpassing over the road.

To this end the preferred forni of the invention consists of rails whichare longitudinally divided on a central vertical plane. The two sectionsof each rail thus formed are bolted or otherwise secured together, withthe abutting ends of the alining sections breaking joint with thoseforming the opposite side of the rail. Each rail section is constructedwith an extended base iange which is embedded in a road bed of concrete.This bed is assisted in maintaining the rails spaced to the proper gage,by transversely arranged tie-b ars.

Reference is to be had to the accom anying drawings forming a part ofthis speci ication, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a cross section through the preferred form of my invention,and Fig. 2 is a plan of the same, partly in section.

In carrying out my invention, I employ rails l-1, each of which iscomposed of two longitudinal sections 2-2 which, when bolted orotherwise secured together, form a rail having heads and webs of theordinary form. The dividing plane between the two sections of each rail,which is vertical, is preferably centrally located, forming both theouter and inner sections of the same size. The base flanges 3 and 4,respectively, of both the inner and outer sections, are of extendedwidth, with the inner flanges formed with downwardly-turned edges, asindicated. at .5, which hold the rails against lateral displacement whenembedded in a concrete road bedv 6, as indicated. in Fig. l.

AAs shown in Fig. 2, the rail sections of each rail, when securedtogether, are placed so that the abutting ends of two alining sectionsWill break oint with the corresponding sections forming the oppositeside of the rail. By this construction it is possible to reinove eitherthe inner or outer half of the rail without interfering with the otherportion thereof, and thus avoid any interference with the traffic overthe road while taking up and replacing worn or d amaged rail sections.Moreover, since the head of thve rail usually wears out at the inside ofthe trackbefore the outside of the same is materially affected, it ispossible by my invention to replace only that portion of the rail whichis worn, leaving the opposite half int act.

For assisting the concrete road bed 6 in maintaining the rails spaced tothe proper gage, the latter are connected together at the joint of eachrail section and at other points if desired, by transverse tie-bars 7.These tie-bars as shown, are formed with a flat-faced head 8 at eachend, which bears against the inner face of the rail web. Bolts 9 whichconnect the sections of each rail together, are also preferably utilizedfor securing the tie-b ars 7. For this purpose the bolts pass throughthe heads 8 as best shown at the sectional portion of Fig. 2. Theiianges 3 and 4 of each rail are also connected together at the jointsof alining sections, by plates 10 which are 'preferably bolted in place,each flange being thickened` at the point of application of the plate,as best shown in Fig. l, in order to provide sufficient screw-threadsfor the bolting operation.

It is obvious that the construction hereinbefore described maybedeparted from in numerous particulars falling within the scope of theannexed claims.

Having thus described my invention I claim as new and desire to secureby Letters Patent:

l. A railway construction, comprisin rails longitudinally divided on avertica plane forming each into two sections with flat inner faces, eachsection of said rails having extended base flanges, withdownwardlyturned edges formed on the iianges of the inner sections,tie-b ars, unitary means for connecting the sections of each railtogether and att aching said tie-b ars, whereby the flat faces ofopposed sections are forced into contact throughout, and platesconnecting-the base flanges of alining sections together where thesections break joint.

2. A railway construction, comprising rails longitudinally divided on avertical plane forming each into two sections with IIO fiat inner faces,said sections of each rail In testimony whereof I have signed mybreaking jolnt With each other and provided name to this specificationin the presence of lo with an eXtended base flange, means for contWosubscribing Witnesses. neoting the opposed sections of each rail t0-gether, whereby the iat inner faces are forced JOHN H F' SHULZE' intoContact throughout, and plates bolted Witnesses: directly to the top ofthe base anges of alin- W.
